WINDOW.

SPECIFICATION forming partof Letters Patent No. 509,521, dated November2S, 1893.

Application filed April 28, 1893.

To a/ZZ whom t may concern.-

` Be it known that I, OSCAR FRoTscHER, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inWindows, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to certain new and useful improvements in windowsof that class in which provision is made for allowing the sliding sashto be swung out or reversed if desired for cleaning or other purposes,and it has for its objects among others to provide a window of thisclass which can be cheaply made, easily operated and not liable to getout of order.

It has for a further object to provide simple yet efficient means forholding the sash inclined for ventilation; and for a still furtherobject the provision of means for firmly holding the sash in positionfor cleaning.

It aims further at certain improvements in the details of constructionwhereby better results are attained without increasing` the cost ofconstruction or interfering with the employment of the Window in theordinary.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a vertical section of awindowframe, with the sashesin position. Fig. 2 is a similar View, withthe lowersash shown open for ventilation by full lines, and in dottedlines shown open for the purpose of cleaning. Fig. 3 is a like view withthe upper sash open for cleaning, the dotted lines showing the said sashin position for introducing the means for holding it firmly in place,the attachment being shown by full lines in the position it assumes whenextended. Fig. 4 is ahorizontal section through one side of the windowwith the upper sash indicated by dotted lines.

5o Fig. 5 shows in detail the means for holding the sash in its inclinedposition for cleaning.

SerialNo.472,212. (No model.)

Like letters of reference indicate like parts throughout the severalviews in which they occur.

Referring now to the details of the drawings by letter, A designates thewindow-frame, B, the upper, and G the lower sash. The sashes are adaptedto slide in the ways in the frame and are hung upon the cords or chainsl) and Weights E, the former running over the pulleys F arranged in thepulley stiles G in any well-known way. Each of the sashes is cut away orrabbeted on the sides adjoin ing the pulley stiles from about the middleor center ot' its height upward as indicated at a, preferably toward theoutside of the window as shown best in Fig. 4:. Below this rabbet is ahole b to receive the cord or chain D which is knotted or fastened inany suitable manner. The lower sash is of usual size andis held in placebya stop-bead cwhich is divided on both sides of the window at a pointsomewhat above thetop of thelower sashandlhinge them to theframe in anysuitable manneras by hinges d as seen in Figs. 3 and 4. The upper sashis somewhat narrower than the lower one as will be seen from Fig. 4:,and the space thus provided is occupied by the projection e which may beintegral with the pulley stile, or it may be in the form of a cleatseparate therefrom and secured thereto in any suit-` able manner asindicated by dotted lines in Fig. 4; in either form of construction itserves the same purpose. Making the pulley stile thicker than usual andrabbeting the same may be found the preferable way. A parting bead j isaffixed to this projecting portion and extends from the bottom of theupper sash to the window bead as seen in Fig. 4f, projecting about asmuch as the usual parting strip projects from the frame.

The attachment of the cord or chain to the sash is preferably a littleabove the center of gravity of the sash so that it will have a tendencyto revert to its normal position and at the same time will require butlittle exertion to hold it in the position for cleaning. The pulleys Fare preferably of different sizes, the back pulleys being the thicknessof the projection e wider than the front one; by this IOO positions inthe boxes ot' the frame.

Against the head of the window frame in the plane of the upper sash Iplace a stripV g, and on the sill in the plane of the lower sash I placea strip h as seen clearly in Fig. l; the thicknesses of the two combinedbeing somewhat greater than the thickness of the meeting rails so as toallow the upper sash to.move inward as indicated in Fig. 3. These stripsmay be independent pieces secured to the head and sill, or they maybeformed by making these parts of the frame of thicker wood and rabbetingthe same; or the Whole thickness required may be located at the head ofthe window instead of part at the head and part at the sill, as may befound most expedient.

With the parts constructed and arranged substantially as above set forththe operation 'is as follows: The movable portions of the stop-bead arethrown out on their hinges into the position in which the one is shownin Fig. 3; the lower-sash can then be brought forward and taken-out ofthe groove or-way and can thenbe reversed on the cords by reason of thecut away portions, for cleaning the outside; when .returned to itsnormal position it can be slid upward inside of its groove or way. Theupper sash can then be slid downward and at once brought forward out ofits groove or wayas seen in Fig. 3. Owing to the sashes beingvcut awayat the sides as indicated at c theycan beeasily reversed withoutwithdrawingthem entirely out of the frame, whereas if they-were not cutaway, it would be necessary to lift the cords out of the grooves in or-`der to draw out the sashes entirely-clear of thetrame before they couldbe reversed. The lower sash in order to swing inward more easily should.have the outer lower corners rounded oft slightly where they are incontact with the cleat or projection in the groove of the upper sash, asshown at n; as seen in detail at the right of Fig. 4t.

To lprevent the rubbing of the chains or cords against the wood inmoving the sash inward I Vsecure a screw I at the corner of the xedinside stopbead vl and also at the corner of the parting strip at thelower end ot' the same, on both sides of the window; these screws arewithout projecting heads as seen in `Fig. 4.

In order to bring the lower sash inward and hold it in an inclinedposition as shown in Fig. 2 for ventilation I secure a plate J to thepulley stile so that it will hang loosely on eitheror both sides of thewindow; this plate is provided with a plurality of notches j and ispivoted on a screw or other suitable means `lait-being covered by theinside stop bead as seen in Fig. l, which is provided with a recess Z toreceive it as shown in Fig. 3. This plate is beveled on the side of thenotches and is adapted to be engaged over a pin or screw K secured tothe side of the sash and thus the sash can be secured in as manypositions as there are notches in the plate. In

bringing the sash in for cleaning this plate must, of course, bedisengaged from the pin or screw.

In order to hold and support the sash in an inclined position forcleaning I have provided the following means: At one or both sides ofthe window I attach to the inside stop bead above the division a plate Mtapped to receive a thumb screw, and to the side of each sash in therabbet thereof a plate N with an elongated hole nas seen best in Fig. 5,where the plate N is shown detached. O and P are bars or strips eachprovided with an elongated slot o and p respectively as seen in Figs. 3and 5, and mounted to slide in these slots is a thumb screw Q with aplate upon each side of the said strips to bind them together when thethumb screw is turned in the proper direction. One end ofthe plate orbar O isconnected to the plate M by a thumb screw m while one end of thebar or strip Pis provided with a casting R which has a crook r as seenbest in Fig. 5 which is adapted toengage the elongated slot of the plateN. The operation of this part of the inventionis as follows: The

strips or bars being loosely connected bythe thumb screw in the slotsthereof and the thumb screw mengaged with the plate M, thecrook isintroduced into `the elongated `slot n of the plate N when the sash isbrought inward as seen by dotted lines in Fig. 3. The sash is thenbrought inward to an Vangle of about forty-live degrees (450), and asthesash is turned to bring it into this position, as soon asthe sash isturned from an upright position the crook turns in the slot and becomesso fixed that it cannot-be displaced or disengaged until the sashisbrought into its former position, parallel with thestrip P. When thesash has been Vbrought to an angle of about forty-tive degrees, as shownby full lines in Fig. 3, the thumb screwis tightened and the sash willthus be held firmly in that position.

S is an angle plate or iron secured-to one of the bars or strips as seenin Fig. 3, and

-when the bars are brought into the position in which they are shown byfull linesin Fig.

3 it serves as a stop to prevent further movement of the bars andprevents one going beyond the other as will be readily understood vfromreference to Fig. 3. The crook lr being in a-vertical plane about midwaybetween the plates N of the upper and `lower sash can be used foreither.

Modifications in detail may be resorted to without departing from thespirit of the invention or sacrificing anyof its-advantages.

Parts may be used without the whole. The supporting devices .may be usedin connecltion with other constructions of window.

What I claim as new ism l. The combination with a window-frame, of twosashes of different widths, the upper sash being the narrower and eachsash having its edge cut away for a portion of its IOC length, aprojection between the narrow sash and the frame, and a movable stopbead in front of the bottom sash to provide a space below the upper sashfor the withdrawal of the sash, substantially as specified.

2. The combination with a window-frame, of two sashes of dierent widths,the upper sash being the narrower and each sash having its edge cut awayfor a portion of its length, the sustaining cords attached to said sashnear the end of the cut away portion, a projection between the narrowsash and the frame, a parting strip set in front of the upper Sash onlyand a movable stop bead oppo-V site the lower sash, substantially as andfor the purpose specied.

3. The combination with a window frame havingV two sashes hung therein,the sashes and guides for the same being constructed to allow the top ofthe sashes to swing inward and downward, of a plate on the sill of theframe in line with the lower sash and a plate in the head of said framein line with the upper sash, said upper sash being narrower than thelower sash and hung on two cords, one on each side, whereby the top ofsaid sash may swing inward and downward on said cords, under the bottomof the lower sash when the latter is raised, substantially as described.

4. The combination with a sash mounted to swing, of means for holdingthe same in an inclined position, said means comprising two pivotallyand adj ustably-connected slotted bars, screws passing through the slotsfor `adjusting them, and means for detachably 3 5 April, 1893.
